LLDP Is a industry standard protocol that allows devices to advertise, and discover connected devices, and there capabilities.
In this procedure
we are configuring the switch port to advertise supported POE wattage
, VLAN assignment
, and DSCP values the phone will be using.
The VLAN that is being used for VOIP traffic needs to be tagged on the port the phone is connected to.
- configure vlan <VOIP vlan> add ports <port number> tagged
The following mandatory TLVs are not configured by default in EXOS:
- LLDP-MED Capabilities
- LLDP-MED Network Policy
- LLDP-MED Extended Power-Via-MDI TLV
Use the following commands to configure them and allow the switch to communicate with the phone via LLDP:
- enable lldp ports <port number>
- configure lldp port <port number> advertise vendor-specific med capabilities
- configure lldp port <port number> advertise vendor-specific dot1 vlan-name vlan <VOIP vlan>
- configure lldp port <port number> advertise vendor-specific med power-via-mdi
- configure lldp port <port number> advertise vendor-specific med policy application voice vlan <VOIP vlan> dscp 46
- Configure lldp port <port number> advertise system-capabilities
- Configure lldp port <port number> advertise vendor-specific dot1 port-protocol-vlan-id vlan <VOIP vlan>
